Cannot connect power BI dataflow to datalake CDM folder

Hi sayanika .

There are a few considerations and limitations to keep in mind when working with your dataflow storage:

• Linking an Azure Data Lake Store Gen2 account for dataflow storage is not supported in the default environment.
• Once a dataflow storage location is configured for a dataflow, it can't be changed.
• By default, any member of the environment can access dataflow data using the Power Platform Dataflows Connector. However, only the owners of a dataflow can access its files directly in Azure Data Lake Storage Gen2. To authorize additional people to access the dataflows data directly in the lake, you must authorize them to the dataflow’s CDM Folder in the data lake or the data lake itself.
• When a dataflow is deleted, its CDM Folder in the lake will also be deleted.

For more details, please check the online document.
